Tanithar’s Tower is the human structure in the Anvil Cloudlands. It is a wizard’s tower once belonging to the great Tanithar, a mage from a previous age who rivaled the Archmage of that time. He built a refuge in the clouds, and brought with him a number of scribes, apprentices, assistants, and so forth. However, one day he simply did not return, and they had to fend for themselves. Their descendents form the present population of the town. The Tower is a centerpiece of what is now the human settlement of Ouranoupolis, and has been converted into a government building.
The tower is very complex, appearing a little bigger on the inside than it looks from the outside. Some say that there are doors no one knows how to open. Who knows what could be inside?
